TL;DR: In this article, the relative importance of shape-selectivity due to channel size limitations and zeolitic grain size in the conversion of methanol to higher hydrocarbons on Pentasil-type zeolites, several catalysts were prepared using different synthesis and acidification procedures.

TL;DR: In this article, the possibilities of preparing bimetallic catalysts supported on TiO2 (Degussa P-25) by UV illumination (λ > 300 run, radiant flux, 60 MW cm−2), at room temperature for 24 h, of aqueous suspensions containing 500 mg of this oxide, and cations of the desired metals in amounts corresponding to metal loadings between 0.5 and 2.5 wt% if complete reduction were achieved.

TL;DR: In this paper, the influence of the crystallographic arrangement at the surface of a metal-supported catalyst on its catalytic properties has been studied, where catalysts have been prepared with well faceted nickel crystallites presenting particular faces at their surface.

TL;DR: In this article, three series of palladium-based catalysts have been studied by Low Energy Ion Scattering (LEIS) and Transmission Electron Microscopy (TEM).

TL;DR: In this article, the formation and stability of nickel clusters is attributed to the strong reducing potential of the NaH-t-BuONa mixture complexing the nickel clusters, and bipyridyl ligands exert an additional stabilization so that clusters containing less than 10 atoms could be present.
